[AA] [S] Sims dying from overheating/freezing in camp with correct clothing

I've been experiencing the same issue for weeks. I tried using the mccc mod to see if my sim had been flagged for death but she had no flags, and even playing the game without mods or cc my sim dies from overheating everytime I open the same save file. It's winter and freezing temps on my game and I can't even be fast enough to change her outfit or set the thermostat to a different temperature in game because she dies immediately.
